CRISPR-based in situ engineering tumor cells to reprogram macrophages for effective cancer immunotherapy
Nano Today(2022)
Abstract
•A selective responsiveness accelerated gene delivery system was constructed.•The gene delivery system rendered tumor-specific CD47 knockout and engineered tumor cells into factories of IL-12.•Combination of CD47 blockade and IL-12 production synergistically promoted the macrophage-mediated immunotherapy.
